ADOLPH TOELLNER, OF MILWAUKEE, VISOONSIN.

FOUNTAIN-PUMP.

SPECIFICATION forming part of Letters Patent No. 236,650, dated January 11, 1881.

Application filed April 19, 1880. (No model.)

To all who 1 it may concern:

Be it kncwu that I, ADOLPH ToELLNER, of Milwaukee, in the county ot' Milwaukee, and in the State of \Visconsin, have invented certain new and useful Improvements in Fountain- Pumps; and l do hereby declare that the following` is a full, clear, Iand exact description thereof.

My invention relates to pumps; and it cons ists in the device hereinafter claimed.

Figure 1 is a vertical central section. 2 and 3 are details.

A is a horizontal cylinder having an inletvalve at each end. B is a hollow plunger similarly provided with inlet-valves. A slot, B', in the top of the plunger admits a pipe, C, and on the lower end of this pipe I key a crank, c, the arm of which is toggled to one ot' the heads ofthe plungers. The pipeI C lits watertight ina tube, a, on the cylinder, and continues up to and through the basin. Just beneath the basin l key a horizontal bevel-wheel, F, to the pipe C, and this meshes with a vertical bevel-wheel, F', on an axle, F2, from which I suspend a. weighted cord, F3; or the axle may connect with and he driven by a windmill or stean1e1igine.

Operation: Suppose the cylinder is submerged in a cistern and the cord F3 has been wound about the axle. The weight in its descent will cause the cord to revolve the axle, which, in turn, will revolve the pipe and crank. 'Io overcome the dead-centers of the crank I make the axle F2 oval in cross-section, or provide it with an oval sleeve where it receives the cord, and I so time it with the crank that when the latter has reached a deadicenter the greatest width ot' the axle will have passed beyond the vertical, and will be carried over Figs.

with sufficient velocity to make the revolution of the pipe continuous. One turn ofthe crank o will carry the plunger from one end to the other ot' the cylinder and back. I provide, when aJ steady stream is required, an air-chamber, C', into which the pipe() opens, the body of air in the said chamber forming an elastic cushion, against which the water impinges at each stroke, to be forced out h v the expansion of the air between the strokes. Thus, as the pipe is revolved, it will reciprocate the plunger in the cylinder, expelling the water at each half-revolution ot' the pipe as water isforced into it, and by the employment ot' the air-cham ber, or omitting it, a steady or intermittent stream may be ejected.

My pump may he operated by a crank, as shown in Fig. 2, and this may connectl with wind, steam, water, or animal power.

I claiml. The hollow slotted plunger having a valve at each end, and cylinder having corresponding valves, in combination with pipe C, a device for revolving it, crank, and connecting-rods, as set forth.

2. rIhe combination of the axle, made oval in cross section or provided with an oval sleeve, with a weighted cord, pipe, crank attached to the lower end of pipe, connectingrod, plunger having valve at each end, and the cylinder A, having corresponding` valves, as set forth.

ln testimony that I claim the foregoing I have hereunto set my hand.

ADOLPH TOELLNER.
